I had the Tire pressure sensor/flat tire come on in my '05 525i. Checked everything, all was fine, put air in tires etc. Message will not go off, though tires seem to be fine--Not loosing air at all.

Question---Could it possibly be that I was descending a mountain of 11,000 feet at a fairly good rate of speed? Would the sensors have picked up the change in air pressure-decreasing as you go down, and thought I had a flat? It happened about halfway down. Has anyone had this happen? Also, how do I get the warnings lights and message turned off? Thanks for any help!

You know, maybe it does have something to do with altitude. I had a similiar problem just today and I asked the dealer and he told me that was probably the case when I suggested it. I let them look at it anyhow and they told me everything was in working order.
